Info: The Model 145/145E Statistician Calculator gives computational capacity requiring no special skills on your part—just an understanding of the problem to be solved.
Although the calculator is nearly as complex inside as a large digital computer,
operating it is as simple as writing an equation on a sheet of paper—you simply enter the equation in the calculator in the same sequence as you would normally write it.
Then the calculator takes over—using its internal working registers automatically,
so you don’t have to concern yourself about them.
This built-in operating simplicity lets you handle the large amount of routine work required of a desktop calculator with little orientation and training.
Another convenient feature of the calculator —ten data storage registers— lets you save numbers inside the calculator instead of writing them down.
With the Model 145/145E Calculator a touch of a key performs many functions frequently used in scientific and statistical problems.
Besides the basic arithmetic operations, it can perform a full range of statistical functions, such as accumulation of squared data items and paired data information; calculation of mean, standard deviation, and area under the normal curve; and performance of linear regression analysis.
And one have a choice of formats for printing the results:
A mixed decimal fraction format: 123456.1234
An exponential format: 1.234561234 05
Internally, the calculator operates with 14 digits.
The calculator’s operating simplicity makes it almost impossible to make an error,
but you may occasionally try an operation that is mathematically illegal—such as division by zero.
Instead of giving an erroneous answer, the calculator warns you of the error,
so you can correct it at the time it happens and continue calculations with valid data.
An extremely important feature of the calculator is the learn mode programmer (LEMP).
Using this feature, you key the operations or steps to work a problem only once,
and the calculator ‘remembers’ each operation.
Then, it can perform those operations repeatedly, very rapidly, and without error.
All you do is enter the variables.
Even more flexibility is yours with the optional card reader.
With this feature you can use not only the basic keyboard functions but also the internal computer-like instructions.
And you have the added advantage of recording your instructions permanently on punched cards.
The internal instructions available through the card reader include decision-making capabilities for conditional branching and looping as well as instructions that let you manipulate data.
